#1 Trading options in only one direction and that’s usually up.
A common mistake options traders make is one of omission. They forget or fail to realize that options trading allows one to make money on falling prices as well as rising prices. By not trading in both directions they leave a lot of money on the table. When you stop trading when the market is in a downturn, you are potentially leaving half the available money on the table.
Additionally, security prices tend to fall faster than they rise, so some of the biggest, quickest gainers are executed via falling share prices. So if the intrepid options trader is not looking for short trades they are truly cheating themselves out of some of the best trades going.
#2 Not having money-management rules in place.
Another common mistake is to not strictly adhere to sound money-management rules. Critical metrics arise from guiding principles such as how much should you trade and how much should you risk? Where should you set your stops or in what manner should you hedge?
Solid money management rules control help you to control your trades. And most importantly, they help to prevent catastrophic losses so that you can trade another day.
#3 Letting your emotions dictate your trade entry and exit points.
Many times behavior that is illogical makes investors execute trades that lack the necessary fundamentals. Instead of letting sterile indicator guide their decision making, they operate on emotion or impulse. Fear of price reversal drives traders out of winning trades too soon and fear of loss makes them stay in losing trades for too long.
And because there is zero way to eliminate your emotions completely, you must learn to control them. The most realistic and effective way to do so is to develop a set of trading rules to constrict your trading activities and to conduct the majority of your research and trading decisions outside of open trading hours.
